You mean the differences between only the nativity stories? The nativity stories are just about 20 verses long each, Matt 2:1-23 and Luke 2:1-21, there's hardly enough data to draw anything of them, let alone fancy diagrams, it's barely a 15 minutes' reading. If you're intrested in the entire gospels, then there's something to be found, like these kind of analyses from here (where the method is described in further detail):

From the divergent ancestral lineage, to the conflicting dates (Matthew, 4 BCE & Herod; Luke, 6 AD & Quirinius) to the completely made up narrative to get Mary to Bethlehem, to what happened after (Matthew, fled to Egypt to avoid the mythical massacre of the innocents; Luke, return to Nazareth), the differences are legion.
